'This Ainvention relates to containers designed and adapted to contain plastic compositions, and relates generally to means controlling the ejection of the contents from the container,

An object of the invention is to provide an improved container having an end wall attached thereto formed with a central opening, in com bination with a nozzle having a circumferential groove at its inner end receiving the marginal portion of said end wall around said opening and being thereby rotatively supported, a cap rotatively attached to said end wall and having an outer peripheral portion adapted to be manually engaged to rotate said cap, means attaching the inner margin of said cap to said nozzle to rotate the same, and a novel ejector device confined within the container and engaging said nozzle for operation thereby to eject the contents of the container.

'a container having one end formed with an opening,` and novel means for rotatively supporting a nozzle in connection with the marginal.`

erate an `ejector to discharge the contents of ther container through said nozzle.

`Another lobject of the invention is to provide .a novel `type of ejector device in a container embodying the essentials of thecontainer before mentioned. v y A further yobject of the invention is'to provide a container .of the character mentioned havm ing a spiral rod rotatively supported in central position therein and formed with an open frame at itsouter end engaging the rotary nozzle of the container for rotation thereby,kand an ejector mounted on said rod for operation to eject the Ycontents of the container. I

Another object of the invention is tov prevent reverse rotation of said-rod, and thereby eectively prevent refilling the container after it has beenwholly or partially emptied. l

Other objects of the 'invention will be readily apparent from the following description, reference being` made to the annexed drawing, in

, Whichi Fig. 1 is a top plan view of a container `made in` accordance with the present invention.

Fig. 2 is aside elevation of said container. Fig. 3 is an enlarged vertical sectional View on the une y3--3 of Fig. 1. i i Fig. 4 is a transverse sectional view through Another object of the invention is to provide the nozzleand the closure cap on the line 4-4 of Fig.'3. 4 i c Fig. 5 is a transverse sectional View of the container and the ejector rod on the line 5`5 i of Fig. 3.

Fig. 6 is an enlarged sectional view similar to the sectional view of Fig. 3, more clearly showing the construction and arrangement 'of the rotary `nozzle and associated parts. I

Fig. 7 isa side elevation of the nut or` threaded sleeve screwed upon the ejector'l rod. The present invention is embodied in a container comprising an enclosing wall I having permanently attached thereto a bottom wall 2 formed with a central bearing 3.l `The opposite end of the container comprises a wall fi having an annular outerrnargin 5 receiving the upper end of the container wall i and rigidly attached thereto in order to provide a leak-proof joint M end wall 4 is formed with a central opening.

' A nozzle comprising a tubular portion t is rotatively engaged with the margin oi the end `wall i around the opening therethrough. The nozzle il is formed with acircumferential bead l seating closely against the outer surface of the end wall 4 around the `opening therethrough. A groove 8 is formed around the inner end of the nozzle S and receives the inner margin` of the wall t in order to supporty the nozzle rotatively incon-v y5 nection with the Wall 4. Said groove 8 is formed by bending outwardly the inner marginal end S f of the tube 5 so that .the inner margin ofthe between the container l and said end wall 4. The

wall 4 engages in said groove.` The clamping and i frictional engagement of the bead land end por-` tion 9 of the tube ii with the wall 4 vis quite close,

so that a substantially leak-proof joint is pro-` vided, but leaving thenozzle 5 free to rotate with respect to the Aenol Walid. The cuter end of the tube 6 may be turned or rolled inwardly tou form a bead il) that strengthens the tube 6` against bending and prevents the formation of i a sharp cutting edge at the end of the nozzle.

The operating device for rotatingA the nozzle comprises a cap il rotatively seated upon the neither can turn independently of the other, but both must be turned together. The outer margin I4 of the cap I I is in the form of an annular llange encircling and closely contacting the annular outer margin 5 of the end wall 4 and having its edge I5 extending under the margin 5 so as to hold the parts securely in assembled relationship. Thus the end wall 4 is rigidly engaged with the end of the container I and the cap II is rotatively supported by said end wall 4. The outer periphery of the margin I4 may be knurled, or provided with ribs or the like as shown, in order to provide a grip for the thumb or finger of the user to rotate the cap II, and thereby the nozzle 6 and the ejector device.

In the embodiment shown, a spiral rod IG is located at the axis of the container I and has its inner end rotatively engaged in the bearing 3 formed in connection with the bottom end wall 2 of the container. The outer end of the rod I6 is not of spiral form and is bent to form an open frame I'I having at its inner portion lateral extensions I8 engaging under the inner end of the tubular nozzle 6, so that it is impossible to remove or Withdraw the spiral rod I5 from the container. The frame I'I extends into the tubular nozzle G and is engaged by any two diametrically opposite projections I9 formed in connection with said tubular nozzle. When the nozzle Ii is rotated by the cap II in a clockwise direction, as seen in Fig. 4, the spiral rod I6 will also be rotated.

The ejector shown comprises a wall 20 of any appropriate material or composition tting within the container I and having close frictional engagement with the inner surface of said container. This will prevent the wall 20 from rotating with the rod I6. A sleeve or nut 2I has a spiral opening therethrough so as to screw onto the spiral rod I6. This sleeve or nut 2I extends through the axis of the wall 20 and has a flange 22 on one end seating or clamping against said wall 2li and iingers 23 in its opposite end bent laterally and engaged with or extended into the wall 2G. This effectively prevents the sleeve or nut 2l from turning with the rod I6 and seals the opening through the wall 2l) to prevent the passage of the container contents therethrough.

lA removable and replaceable Aclosure cap 24 is provided to telescope upon the nozzle 6. The wall of the closure cap 24 very closely engages the ribs or projections I3 in order to hold the closure cap securely on the nozzle but to permit withdrawal thereof when it is desired to eject a portion of the contents of the container I.

If desired, reverse rotation ofthe ejector device may be prevented, thereby making it impossible to refill the container or replace any part 0I" the contents thereof.

One or more resilient tongues 25 may be formed in connection with .or attached to the cap II and caused to engage successively in indentations 26 formed in the wall 4. These tongues 25 will permit turning of the ejector device in a direction to eject the contents of the container, but will prevent turning of the ejector device in the opposite direction to movethe wall 2D inwardly toward the bottom wall 2 of the container.

It is now apparent that this invention attains all of its intended objects and purposes efficiently,

economically, and satisfactorily. The device may be varied within the scope of equivalent limits without departure from the nature and principle of the invention.
